CHARLES F. RAYMOND, OF BIRMINGHAM, ALABAMA.

IMPROVEMENT IN TALLOW-CL JPS.

Specification forming part of Letters Patent No. 212,262, dated February11, 1879; application filed October 10, 1878.

To all'whom it may concern:

Be it known that I,O11AnLns F. RAYMOND, of Birmingham, in the county ofJ efferson and State of Alabama, have invented certain new and usefulImprovements in Tallow-Cups and I do hereby declare that the followingis a full, clear, and exact'description thereof, reference being had tothe accompanying drawings, and

Figure 1 is a side elevation of my improved lubricator. Fig. 2 is acentral vertical section of the same. Fig. 3 is an interior view of theplug; and Fig. 4 is a section of the frame, showing the stop for theplug.

A represents the oil cup or reservoir, with cap B screwed in the topthereof. In the bottom of the reservoir is screwed the brass frame.

0, containing the plug D. The plug is hollow, with a central partition,D dividing the interior in two chambers, D D", having outletports a a tocorrespond with passages I) b in the bottom of the frame 0, foradmitting the oil from the chambers D in the plug to the steam-chests.

The upper end of the partition D terminates in a point, (I, whichdivides the inlet-opening 6, so that the oil will run into both thechambers D said inlet-opening c coinciding with a passage, f, for theadmission of oil, or with an airpassage, h, for the admission of air,the

same as described in my former patent aboye referred to.

In the sides of the partition D are made dovetailed grooves 00 w toreceive corresponding plates E E, for the purpose of diminishing thesize of the chambers D, so as to hold just the quantity of oil requiredfor one oiling.

The air-passage h in the present case extends through the top of theframe 0, and in the upper end thereof is screwed a pipe, F, which passesup through the reservoir, and has at its upper enda cap, G, forming avalve-seat, and incloses an upwardly-closing valve, m.

The cap G is locatedin a recess or chamber,

3 in the reservoir-cap B, and from this recess- 0r chamber extends apassage, 6, through the cap B, as shown. In the upper end of the passage'5 is an air-valve, n.

WVith my lubricator as constructed according to my former patent abovereferred to, I could only oil the valves when the engine was rolling orwhen not using steam. With my present improvements I can oil the valveswhen the engine is using steam or not, just as desired, by not havingthe air-hole in the side of the frame, but having the air-tube F running from the neck of the frame 'up through the reservoir with the valvemin the top, which keeps the steam from blowing the oil from thechambers back into the oil-cup.

The valve n in the top of the air-passage z in the reservoir-cap B is soarranged that it will remain closed and keep the oil from being thrownout by the motion of the engine. If it should be desired to oil thevalves when the engine is rolling or not using steam, the cylindersmakea strong suction, which will raise the valve in the cap and allowthe air to pass in through the air-passage and tube F into the chambersto give them vent, so that the oil will run down into the steam-chest.

The valve m in the top of the air-tube F will remain open, except whenusing steam, and allows the air to pass from the chambers up into thereservoir when the chambers are filling.

The plug D is attached to a stem, I, and on this stem is secured asegment, H, which acts as a stop against parts of the frame to keep theplug from turning too far. I also employ a spring, J, on the stem tohold the plug tight in its place and keep it from leaking. The tensionof this spring is regulated by means of set-nuts K on the stem, as shownin Fig. 1.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The plug D, provided with central partition D1, having doyetailedgrooves or recesses a: :0 in its sides, in combination with the platesE, for the purposes herein set forth.

2. The combination, with the plug D, constructed as described, of theframe 0, with airpassage h, the tube F, with cap G and Valve m, and thereservoir-cap B, with air-passage '5, substantially as and for thepurposes herein set forth.

3. The combination of the plug D, stein I,

stop H, spring J, and regulating-nuts K, all constructed and arranged tooperate substantially as and for the purposes herein set forth. Intestimony that I claim the foregoing as my own I affix my signature inpresence of two witnesses.
